Currently the x86 platform devices are not consistent about selecting
or depending on the LEDs Kconfig variables, and this inconsistency
leads to Kconfig getting upset and refusing to offer LEDs (even on
non-x86 platforms):

drivers/platform/x86/Kconfig:422:error: recursive dependency detected!
drivers/platform/x86/Kconfig:422:       symbol EEEPC_WMI depends on ACPI_WMI
drivers/platform/x86/Kconfig:438:       symbol ACPI_WMI is selected by ACER_WMI
drivers/platform/x86/Kconfig:18:        symbol ACER_WMI depends on LEDS_CLASS
drivers/leds/Kconfig:10:        symbol LEDS_CLASS is selected by EEEPC_WMI

Fix this by always selecting rather than depending on the symbols as
slightly more drivers use this approach already and it seems more
user friendly.

The old code was using platform_driver.probe to initialize
eeepc_wmi context. That's a mistake because if probe fail,
eeepc_platform_register() won't tell anyone, and chaos will happen.

Wrap add and remove code inside eeepc_wmi_add() / eeepc_wmi_remove(),
and try to use the static platform_device only in eeepc_wmi_init()
and eeepc_wmi_exit()

The code is now very similar to eeepc-laptop, except eeepc_laptop_add
and eeepc_laptop_remove are called from acpi_driver, not module
init/exit functions, but WMI doesn't provide such functionalities (yet ?).

We don't need to call bios/acpi (cmpc_set_rfkill_wlan) if the blocked
state is already set to the same value (little optimization). This can
happen for example if we initialize the module with same initial
hardware state (rfkill core always call cmpc_rfkill_block on
initialization here).

Also GWRI method only accepts 0 or 1 for setting rfkill block, as can be
seen on AML code from acpidump->DSDT from a classmate sample I have, so
should be fine setting state only to 0 or 1 directly.

WMI data blocks can contain WMI events with the same GUID but with
different notifiy_ids, for example volume up/down hotkeys.
This patch enables a single event handler to be registered and
unregistered against all events with same GUID but different
notify_ids.  Since an event handler is passed the notify_id of
an event it can can differentiate between the different events.

The patch also ensures we only register and unregister a device per
unique GUID.
